There have now been fifty Eurovision Song Contests, since the first event staged in Lugano Switzerland on Thursday 24th May 1956. There were only seven competing nations on that occasion, and uniquely each country had two songs in competition, and the full voting was kept private, with only the winner being made public. The 1957 and 1958 contests each had ten competing songs, making them the smallest contests. With more countries joining the competition since 1993, a system of relegation was introduced to limit the number at each contest. However since 2004 a new semi-final system was introduced, which allowed any all interested countries take part. 

Over the next few months I will be providing a review and information on every Eurovision Song Contest, including voting grids.
